How to Get Into ASUS BIOS – A Comprehensive Walkthrough for 2024

Accessing the BIOS (Basic Input/Output System) on an ASUS desktop or laptop is crucial for modifying key system settings and hardware configs. But for many users, entering the ASUS BIOS to make changes can be a bit intimidating.

In this comprehensive guide, I‘ll walk you through everything you need to know about navigating the ASUS BIOS interface. I‘ve built PCs with ASUS components for over 10+ years and am happy to share my insights!

What Exactly is the BIOS?

The BIOS is low-level firmware embedded in the motherboard of your ASUS device. When you first power on your computer, the BIOS is responsible for initializing and testing the hardware like the CPU, RAM, GPU, drives, and more.

It provides a basic interface to change configurations before loading the operating system. The BIOS also governs communications between the hardware and OS during normal operation.

These days, most ASUS boards use a newer interface called UEFI (Unified Extensible Firmware Interface) that replaces the legacy BIOS. UEFI offers better graphics, mouse support, faster boot times, and larger storage support.

When You‘ll Need to Access the ASUS BIOS

Some common reasons you may need to access the BIOS on your ASUS device include:

  • Changing the boot order of devices like drives or USB sticks.
  • Enabling DOCP/XMP profiles for RAM overclocking.
  • Tweaking voltages, multipliers, and frequencies for manual CPU/GPU overclocking.
  • Enabling or disabling hardware components like sound cards, network adapters, SATA ports, etc.
  • Updating or rolling back the BIOS/UEFI firmware.
  • Troubleshooting issues like sudden crashes or boot failures.

I personally needed to recently update my ASUS Z690 board to support my new 13th Gen Intel CPU. Accessing the BIOS was required to upgrade the firmware and tweak settings.

Step 1: Restart Your ASUS Computer

The first step is to fully shut down your ASUS desktop or laptop. Make sure to power it off completely.

Once it‘s switched off, press the power button again to boot it back up. You‘ll need to access the BIOS during this restart process.

Step 2: Know the Correct ASUS BIOS Key

As soon as you press start, you‘ll need to press the appropriate function key to enter the BIOS. The correct F key can vary based on your specific ASUS model.

Some common ASUS BIOS keys include:

  • F2 or Del – Most desktops and gaming laptops
  • ESC – Some older netbooks/laptops
  • F10 – Select notebook models

Consult your ASUS manual or quick start guide to confirm which key you need to press. If unsure, try F2 or Del first.

Also keep in mind that some devices require you to press the key repeatedly, while others may need you to hold down the key.

Step 3: Access the BIOS During POST

POST stands for Power-On Self-Test. This is the initial procedure that runs immediately after you power up your ASUS device.

During POST, you‘ll see the ASUS logo splash screen as the system runs a check on the hardware components.

This is the critical point where you‘ll need to press the BIOS key continuously or hold it down to bring up the UEFI/BIOS menu. The key press needs to register before the Windows OS boot animation takes over.

Here‘s a visual guide to the approximate timing:

If you miss the timing, let the system fully start up, then shut down and restart again to try entering BIOS once more.

Step 4: Navigate the ASUS UEFI BIOS Interface

Once you successfully access the firmware settings, you‘ll be greeted by the UEFI BIOS dashboard. This will let you configure and tweak system settings.

Use the arrow keys to navigate between the various menu options. Press Enter to select a menu or value.

Here are some key ASUS UEFI sections and their functions:

  • Main – See system info like CPU, RAM, drives. Can change time/date.
  • Ai Tweaker – Overclocking menu for CPU, RAM, and GPU.
  • Advanced – Adjust CPU, storage, USB, NVMe, and other system settings.
  • Monitor – View system temps, fan speeds, voltages.
  • Boot – Set boot order and priority. Select boot mode like CSM or UEFI.
  • Tool – Flash BIOS, secure erase drives, and other tools.
  • Exit – Save changes and exit BIOS.

The layout and naming will vary based on your ASUS motherboard model but the core options are similar. Refer to your manual for board-specific menus.

Step 5: Change BIOS Settings Carefully

I suggest caution when changing BIOS values since incorrect settings can sometimes prevent your ASUS device from booting properly. Make incremental changes one at a time.

Some common tweaks include:

Boot Order – Prioritize boot devices like your SSD or HDD higher over optical drives and USB sticks.

DOCP/XMP – Enable these pre-saved profiles for overclocking your RAM above standard JEDEC speeds.

Secure Boot – Can enable or disable this security measure. May impact booting other OSes.

RGB Lighting – Control ASUS AURA Sync lighting effects and colors.

Smart Fan Control – Set custom fan curves for CPU and chassis fans based on temps.

For overclocking the CPU, GPU, or RAM manually, take time to research safe recommended voltages and clock speeds. Stress test for stability between incremental changes.

Step 6: Save Changes and Exit ASUS BIOS

After making your tweaks and changes in UEFI, you‘ll want to properly save the settings and exit.

Navigate to the Exit tab and select:

  • Save Changes and Reset – To save changes and restart the PC.
  • Discard Changes and Exit – To cancel any changes made.
  • Load Optimized Defaults – To revert to factory default settings.

Finally hit Enter to confirm your choice and let your ASUS device reboot normally. Enjoy your new BIOS configs!

BIOS Updating and Recovery Tips

  • Use ASUS EZ Flash in the Tool tab to safely update the BIOS firmware.
  • Enable BIOS Flashback for recovery and updates without entering the firmware.
  • Reset CMOS by shorting the jumper pins to revert BIOS when issues arise.
  • Resolve keyboard errors by using a PS/2 keyboard which works independently.

With this beginner‘s guide, you now have the essential steps to start accessing and configuring the ASUS BIOS or UEFI firmware like a pro. While it may seem intimidating, the BIOS is your gateway to optimizing performance and customizing your ASUS motherboard or laptop.
